A case of disseminated intravascular coagulation (DIC) presenting after surgery for facial trauma associated with multiple facialbone fractures is described. With regard to the oral and maxillofacial region, DIC has been described in the literature followinghead trauma, infection, and metastatic disease. Until now, only 5 reports have described DIC after surgery for facial injury. DICsecondary to facial injury is thus rare. The patient in this case was young and had no medical history. Preoperative hemorrhage orpostoperative septicemia may thus induce DIC.

1. Introduction

Disseminated intravascular coagulation (DIC) is a dynamicpathologic process in which thrombin forms within the vas-cular system [1]. DIC is commonly associated withmalignantneoplasm,major trauma, head injury, infection, and obstetriccomplications [2]. With regard to the oral and maxillofacialregion, DIC has been described in the literature followinghead trauma, infection, and metastatic disease [3]. However,a review of literature shows only a small number of reportsdescribing DIC in relation to oral and maxillofacial surgery[4]. In particular, few reports have mentioned DIC aftersurgery for facial injury. We report herein a rare case of DICafter surgery for facial trauma associated with multiple facialbone fractures.

2. Case Presentation

A 21-year-oldmanwas brought to the emergency departmentat Yamagata University Hospital after becoming involved ina traffic accident while riding a motorbike. On arrival, hewas fully conscious and complained of facial pain. Clinicalexamination showed facial swelling, persistent intraoral andnasal hemorrhage, and bloody otorrhea from the left ear.He showed gross malocclusion associated with discontinuity

andmobilization of themaxillary andmandibular dentitions.He had no significant medical history and had been healthybefore the accident. Computed tomography (CT) and plainradiography revealed right pulmonary contusion, fractures ofa second rib and the right radius, and airway narrowing. Inthe maxillofacial region, bilateral condylar and mandibularfractures, LeFort II-type fracture, and blow-out fracture ofthe orbit were recognized (Figure 1). Airway control wasachieved by awake orotracheal intubation. Hemostasis wasperformed by suture compression for oral hemorrhage andby gauze tamponade for nasal hemorrhage under local anes-thesia, although nasal hemostasis proved extremely difficultto achieve. Respiratory management with a ventilator wasconducted under intravenous sedation until general condi-tion was stable. After another 2 days, the tracheal tube wasremoved, because no airway narrowing or obstruction wasevident. Six days after the accident, tracheotomy and reposi-tioning and fixation of the fractured facial bones, includingthe mandible, maxilla, zygoma, and blow-out fracture of theorbit, were performed under general anesthesia (Figure 1).Surgery lasted 7 h 16min, with 30mL of intraoperative bleed-ing. Intraoperatively, the patient received blood transfusion of2 units of red blood cell concentrate due to low hemoglobinlevels (7.3 g/dL).The postoperative course was uneventful. Onpostoperative day 5, however, fever over 39.0∘C and shivering

were noted. Laboratory examination showed increases in thewhite blood cell count to 14,060/𝜇L and C-reactive protein(CRP) to 12.1mg/dL and a decrease in platelets to 131 × 103/𝜇L(down from 238 × 103/𝜇L at the time of the accident). CTrevealed no abnormalities other than those at the surgicalsites. The next day, the patient showed preshock status witha significant decrease in blood pressure, fever over 39.0∘C,and transient loss of consciousness. Emergency laboratorytests showed increases in CRP to 23.9mg/dL, TBIL to2.1mg/dL, creatinine to 0.97mg/dL, lactate to 4.07mmol/L,prothrombin time to 21.7 s, FDP (fibrin degradation product)to 10.8 𝜇g/mL, and PT-INR (prothrombin time-internationalnormalized ratio) to 1.86, along with a decrease in plateletsto 46 × 103/𝜇L (Table 1). The bacteria was not detected inseveral tests of blood culture. In the evaluation of respiratorysystem, PaO2 was 68.2mmHg, PaCO2 was 28.2mmHg inblood gas analysis, and PaO2/FiO2 was 341. In circulatorydynamics, noradrenaline was administered sustainably by0.04/ for keeping of blood pressure. In the evaluation ofcentral nervous system, Glasgow Coma Scale was E4V5M6and a total of 15. Therefore, SOFA (sequential organ failureassessment) score was 9. From the above results, septicshock was diagnosed and the patient was sent to the inten-sive care unit (ICU). According to the scoring algorithmcriteria established by the Japanese Association for AcuteMedicine (JAAM) for DIC [21], the patient scored 5. DICwas therefore diagnosed and treatment was initiated. To treatsevere infection, cefozopran hydrochloride and freeze-driedpolyethylene glycol-treated human normal immunoglobulinwere applied by intravenous injection empirically. A totalof 38,840 units of thrombomodulin 𝛼 was administeredfor the treatment of DIC. After another 7 days, laboratorytests showed a return to nearly normal state, with CRP of

4.09mg/dL; TBIL of 0.6mg/dL, Crea of 0.67mg/dL, WBC of12,160/𝜇L; platelet count of 175 × 103/𝜇L; prothrombin timeof 13.7 s; FDP of 5.3𝜇g/mL; and PT-INR of 1.17 (Table 1). Thepatient was thenmoved to a general ward and the subsequentcourse was uneventful.

3. Discussion

In the oral and maxillofacial region, several reports havedescribed DIC in patients with oral cancer [17], infection [11],injury [3, 13, 16, 17], orthognathic surgery [12], and toothextraction [5–10, 14, 15, 18, 19]. To the best of our knowledge,however, the English literature contains only 19 reports ofDIC in relation to oral and maxillofacial surgery except fororal cancer (Table 2). This means that DIC associated withoral and maxillofacial surgery is uncommon. Of these 19cases, the most frequent surgery associated with DIC wastooth extraction, in 10 cases. On the other hand, includingour case, only 5 cases involved facial injury related to DIC.Table 2 also shows the diseases underlyingDIC,with prostaticadenocarcinoma and aortic aneurysm in 4 cases each, andsepticemia in 3 cases. Among the 5 cases of facial injury,each patient showed prostatic adenocarcinoma, abruption,septicemia, or no underlying disease. In the remainingcases, Morimoto et al. [17] did not discuss the causativeunderlying disease. The present patient had no medical his-tory before the traffic accident and preoperative hemostaticfunction tests yielded normal results. Two reasons couldexplain DIC in the present case. One is septicemia associatedwith severe postoperative systemic inflammatory responsesyndrome (SIRS). Postoperative stress seemed to not onlyinduce SIRS but also increase its severity. Under severe SIRS,DIC may have developed from hypercoagulability because of

abnormally high activity of a chemical mediator [22]. Theother is persistent intraoral and nasal hemorrhage after theaccident. Laboratory testing showed prominent decreases inhemoglobin (14.7 g/dL to 7.3 g/dL) and platelets (23.8× 104/𝜇Lto 9.8 × 104/𝜇L) between the first visit and the surgery. DICwas possibly triggered in the patient from the large volume ofblood loss, consumption of platelets and coagulation factorsby acute massive hemorrhage, and a high volume of bloodtransfusionwithin a short period [22, 23]. Under such generalconditions, the patient had already been in a chronic stateof DIC before surgery, and this served to aggravate thesymptoms.

The occurrence of DIC is difficult to predict in casesinvolving young patients with no underlying disease, asin the present case. Over the last 20 years, no fatal casesof DIC have been reported in association with oral andmaxillofacial surgery (Table 2).Therefore, in cases with facialinjury, symptoms must be detected and progression of DICprevented by careful perioperative management.
